Penguins are flightless birds that spend half their time on land and half in the water.

1. They have dark and white feathers，and their wings have evolved into flippers(脚蹼).Most penguins feed on fish，squid and other forms of sea life caught while swimming.

2. They are mostly found in groups that include thousands of penguins.Penguins each have their own unique mating call，and they use that to locate their mate and chicks in such a large group.

Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold Antarctica.3. Several species are even found in the temperate zone, and one species，the Galátpagos penguin，lives near the equator(赤道).

Unfortunately, many penguin species worldwide are facing threats.The biggest is climate change and global warming. As the earth warms up，the sheets of ice have melted，and the algae(藻类)that grow under the ice decrease.The algae are eaten by tiny creatures called zooplankton. When there is a drop in zooplankton, it affects the fish that depend on it.4.

Another major threat is from oil spills. If coated with oil, penguins cannot float or swim in　 water. Also, if oil is swallowed, penguins will die from poison.5.

A.These birds are very social.

B.In fact, only a few of them live so far south.

C.Penguins are highly adapted for life in the water.

D.The biggest threat for penguins comes from humans.

E.They have a tendency to live in a community together.

F.As a result，penguins have less fish to eat and thus starve.

G.Others include overfishing，illegal egg harvesting，and natural enemies.

Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer ― migrating birds fly in a "V" to save energy, according to a study published in the journal Nature.

When a bird flaps(振翅) its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost（抬高） from the rising air and therefore use less energy to stay in the air.

Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward.

"They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC.

In fact, the "V" formation has long thought to help birds fly more efficiently(效率搞地). A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof.

"For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies — helping them understand how they can imitate that with their plane formations to save fuel, said Portugal."

1.What is the author's purpose in writing this article?

A. To explain how birds benefit from migration.

B. To introduce how migrating birds find their way.

C. To tell some applications of migrating birds' "V" formations.

D. To report new findings about migrating birds' "V" formations.

2. According to the recent study, when birds migrate         .

A. they don't change their lead birds during the whole journey

B. they fly in "V" formations to protect themselves against enemies

C. they form the shape of a "V" to make best use of the lifting effect

D. the air they stir around makes it hard for the birds behind to fly fast

3.What is the significance of the new study according to this article?

A. It might inspire aircraft companies to think of ways to improve efficiency.

B. It has proved that the "V" formation can improve in efficiency in many fields,

C. It has led scientists to discover that birds' heart rates go down when they fly in a "V".

D. It shows that the best formation of jet fighters in battle should be a "V" formation.

4. The underlined word "imitate" in the last paragraph most probably means "            ".

A. use                    B. copy                C. change                D. learn

A new study has found that North American migratory birds (候鸟)have been getting smaller over the past 40 years. Researchers say the finding suggests a warming climate could be affecting bird growth in North America - and across the world.

The study involved data on nearly 80,000 birds killed from 1978 to 2016 in the city of Chicago, Illinois. Researchers measured the size of the birds. The birds included in the study had died after crashing into buildings during the spring and fall migrations.

Fifty-two species of birds were studied. Most were different kinds of songbirds. These birds reproduce in cold areas of North America and spend their winters in areas south of Chicago. Over the 40-year period, body size decreased in all 52 species. The average body mass fell by 2. 6 percent. Leg bone length dropped by 2. 4 percent. The one area of growth was the wingspan, which increased by 1.3 percent. The researchers said the wing growth likely happened to permit the birds to continue making long migrations with smaller bodies.

Brian Weeks, a biologist at the University of Michigan's School for Environment and Sustainability, helped lead the research. He told the Reuters news agency that he believes the results show a clear link between a warming climate and the growth of the birds.

The study found a direct link between the average summer temperature and the body size of the birds. Dave Willard works with Chicago's Field Museum, which was in charge of measuring all the birds. He said nearly “ everyone agrees that the climate is warming, but examples of just how that is affecting the natural world are only now coming to light.” The study provides new evidence of worrisome developments for North American birds.

A study published in September documented a 29-percent drop in the bird population in the United States and Canada since 1970. The study said this represented a net loss (净亏损)of about 2. 9 billion birds. Weeks said the new study is the largest examination yet to measure body size reactions to warming temperatures involving a large, diverse group of species. “We had good reason to expect that increasing temperatures would lead to reductions in body size, based on previous studies,” Weeks added. “The thing that was shocking was how consistent it was. I was incredibly surprised that all of these species are responding in such similar ways.”

The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings. They will also further examine the idea that an individual's physical development can change to fit changing environmental conditions.

1.In the study, the size and mass of birds fell but the wingspan increased, which　　 .

A.permitted birds to fly higher and stronger

B.made birds' long migration with smaller bodies possible

C.could protect birds from being extinct in the world

D.made North American migratory birds more beautiful and charming

2.Which of the following statements about Dave Willard is CORRECT?

A.He conducted a research which proved the climate is warming.

B.He provided new evidence of worrisome developments for North American birds.

C.He works with Chicago's Field Museum and is in charge of measuring all the birds.

D.He agrees that evidence proving a link between global warming and nature is just revealed.

3.According to the text, what made Brian Weeks astonished?

A.All species are responding to global warming similarly.

B.His study was surprisingly consistent with other scientists' research.

C.Birds got smaller in all parts of their body with the temperature increasing.

D.All species surveyed became smaller in response to increasing temperatures.

4.What would be the best title for the text?

A.Birds Are Going to Die Out

B.Migratory Birds Are Getting Smaller

C.Climate Change May Be Causing Smaller North American Birds

D.Brian Week, A Great Biologist, Published A Study about Birds
